IMPROVEM ENT IN VEGETABLE-PARERS.

Specification forming part of Letters Patent No. 213,880, dated April 1,1879; application filed December 26, 1878.

To all whom it may concern.-

Be it known that I, HENRY EHMANN, of the city of St. Louis and State ofMissouri, have invented certain new and useful Improvements on VegetableParing and Cutting Machines, of which the following is a specification:

The nature of my invention consists in, first, the construction of aparer-rest, which can be set by hand on and off a leading-screw, readyto pare or cut the vegetable while the machine is in motion, and whichis also automatically pressed against and the pressure regulated towardthe center of the receiver of the vegetable, according to the resistanceof the latter; second, the simultaneous rotation by a pair ofspur-wheels of the vegetable, inserted between a receiver and atightener, to prevent a side motion of the vegetable, and of aleading-screw carrying the parer-rest, which by its circularconstruction allows the knife a more or less inclination to thevegetable if pressed toward the center of the latter.

The accompanying drawing shows in Figure I a front view of the machine;Fig. II, a vertical section of the same.

A represents a frame, provided at a with a thumb screw to adjust thesame to any table; at a with a box, in which the vegetablereceiver Brevolves; at a with boxes, in which the leading-screw C revolves, both Band 0 combined by a pair of spur-wheels, D, with a guide, a containingthe adjustable back-center tightener E, and with boxes (0 in which thepress-frame F swings parallel with the leading-screw 0.

Around the axis of F a coiled spring, G, is wound, and fastened with endg to it, the other end, 9 resting in a ratchet, a attached to frame A.

The vegetable-receiver B is an S -shaped knife, the convex sides of itsblade pressing against the vegetable, and so preventing the splitting ofand the turning in the same.

Back-center tightener E is concentric to the axis of thevegetable-receiver B. H is an S- shaped knife attached to end ofleading-screw O, and pointed toward the end of its blade, revolving withthe concaved sides of its blade against the vegetable, by means of whichit gives a steady center excavation of the eye in the vegetable. I isthe parer-rest, constructed of two angular levers, z" and i swinging attheir fulcrum, forming two jaws, a and y. One pair, .10, is used as ahandle, kept expanded by spring i while the other pair, y, is shut, andacts as a nut to leading-screw C. The lever 11 has a prolongation at yeccentric to the axis of the vegetable-receiver B, and having at its enda slithole, i to receive and adjust, by means of a thumb-screw, theknife-shoe K, on which the paring-knife L is attached.

The frame F presses, by means of spring G,

against the handle of the lever 41, the nut forming at 3 a fulcrum ofthe parer-rest I, and by this pressing the knife L against the axis ofthe vegetable-receiver-B. The paring-knife L is V-shaped, rounded off atthe point, to allow the same to cut all irregularities of the vegetablesidewise, as well as with the point.

The guiding part 7c of the knife-shoe K acts as a support on thevegetable, to regulate the deepness of the paring by adjusting the knifeon a desired degree to the parer-rest I.

By tightening the spring G at g through ratchet a the pressing power offrame F can be increased, so that the knife acts deeper toward the axisof the vegetable, cutting sidewise and slicing up the same.

To operate this machine, the vegetable is set on the receiver B, thebackcenter tightener E pushed into the vegetable, the parerrest nutopened by compressing the two leverhandles together, and moved back tothe end of the vegetable. After having set the knife to the desireddepths for paring, and regulated the spring G by means of ratchet a,according to hardness and resistance of the Vegetable, bring thespur-wheels D in motion, through crank or equivalent, till the paring orcutting is done.

The machine will be made out of iron or any other suitable material.

What I claim as my invention, and desire to be secured by LettersPatent, is-

1. The combination of the rest I, screw 0, frame F, spring G, ratchet aand receiver B, as set forth.

2. The combination of the screw 0, knife L, rest I, frame F, tightenerE, receiver B, and spur-wheels D, as set forth.
